What are these and should I be concerned?

This happens when automatically cloning or pulling the repositories; depending on the bandwidth of the connection between you and github, the git request may time out. Previously this condition was not handled; however, some work was done (not by me) to the "download" script to get it to detect failures and attempt a number of retries. Assuming that code works, then it's okay. If you have reason to believe that libraries are not getting downloaded correctly, please let me know.

ok thank you @Tim Edwards
